Tolerances For industrial motors to EN 60034-1, certain tolerances must be allowed on guaranteed values, taking into consideration the necessary tolerances for the manufacture of such motors and the materials used. The standard includes the following remarks: 1. It is not intended that guarantees necessarily have to be given for all or any of the items involved. Quotations including guaranteed values subject to tolerances should say so, and the tolerances should be in accordance with the table. 2. Attention is drawn to the different interpretation of the term guarantee. In some countries a distinction is made between guaranteed values and typical or declared values. 3. Where a tolerance is stated in only one direction, the value is not limited in the other direction. Values for Efficiency () (by indirect determination) Power factor (cos ) Slip (s) (at rated load and at working temperature) Breakaway starting current (IA) (in the starting circuit envisaged) Breakaway torque (MA) Pull-up torque (MS) Pull-out torque (MK) Moment of inertia (J) Tolerance - 0.15 (1 - ) at PN 150 kW - 0.1 (1 - ) at PN &gt; 150 kW 1 - cos , minimum 0.02, maximum 0.07 6 ± 20 % of the guaranteed slip at PN 1 kW ± 30 % of the guaranteed slip at PN &lt; 1 kW + 20 % of the guaranteed starting current (no lower limit) - 15 % and + 25 % of the guaranteed breakaway torque (+ 25 % may be exceeded by agreement) - 15 % of the guaranteed value - 10 % of the guaranteed value (after allowing for this tolerance, MK/MN not less than 1.6) ± 10 % of the guaranteed value

Anti-condensation heater On request, motors which due to strong temperature fluctuations are exposed to condensation during standstill, can be fitted against surcharge with an anti-condensation heater (space heater). For supply voltage and heater rating please refer to the following table: Frame size 112 - 160 Supply voltage (V) 110 or 230 Heater rating per motor (W) 40

During operation of the motor, the heating must be switched off.

Noise The noise level of an electrical machine is determined by measuring the sound pressure level in accordance with curve A of the sound level meter to EN 60651 and is indicated in dB (A). The permitted noise levels of electrical machines are fixed in EN 60034-9 (IEC 34-9). The noise level of our motors is well below these limit values. Air-borne sound measurements are carried out in an anechoic testing chamber to EN 21680ISO 1680. Speed corresponding to a mains frequency of 50 Hz and the number of poles.

Noise levels The noise values listed below refer to 50 Hz at rated voltage with a tolerance of up to + 3 dB(A). Values for pole-changing motors on request. For 60 Hz supply values are 3-5 dB(A) higher. Sound pressure level LpA and sound power level LWA for three-phase single-speed motors with dimensions and output ratings to IEC 60072

Within the rated motor voltage range, the permissible maximum temperature is not exceeded. When the motors are operated at the limits of the voltage tolerance, the permissible overtemperature of the stator winding may be exceeded by 10 K. Nameplates are marked with the maximum rated currents within the stated voltage ranges. For brake motors, for motors in 500 V, 50 Hz design, and all not standard voltages, no voltage range is marked. The voltage tolerances to EN 60034-1 apply.

Rated frequency Three-phase 50 Hz motors can also be operated on 60 Hz mains, provided the mains voltage increases proportionally to the frequency. The relative values for starting and breakaway torque remain nearly unchanged and slightly increase for the starting current. The rated speed increases by the factor 1.2 and output by factor 1.15. Should a motor designed for 50 Hz be operated at 60 Hz without the voltage being increased, the rated output of the motor cannot be increased. Under these operating conditions, rated speed increases by factor 1.2. The relative values for starting and breakaway torque are reduced by factor 0.82 and for starting current by factor 0.9. Additionally to the voltage range for 50 Hz operation, three-phase single-speed motors (not brake motors) are also marked with the voltage range for 60 Hz operation.

Output The outputs stated in this catalogue are for constant load in continuous running duty S1 according to EN 60034-1, based on an ambient temperature of 40° C and installation at altitudes up to 1000 m above sea level. For severe operating conditions, e.g. high switching rate, long run-up time or electric braking, a thermal reserve is necessary, which could call for higher thermal class or the use of a motor with a higher rating. In these cases we recommend to enquire with detailed information on the operating conditions.

Overload At operating temperature three-phase motors are capable of withstanding an overload for 15 seconds at 1.6 times the rated torque at rated voltage. This overload is according to EN 60034-1 and will not result in excessive heating. Utilizing thermal class F, motors can be operated continuously with an overload of 12 %. Nevertheless this is not valid for motors which to catalogue are utilized to thermal class F.

Thermal protection The decision on a particular type of thermal protection should be taken according to the actual operating conditions. Motors may be protected by means of current-dependent thermal protection switches, overcurrent relays and temperature detectors. Thermal protection is possible as follows: · Thermal protection switch with bimetal release · Thermistor protection with semiconductor temperature detectors (PTC) in the stator winding in connection with release (if required, with additional motor protection switch). · Bimetal temperature detector as N/C or N/O in the stator winding (if required, with additional motor protection switch). · Resistance thermometer for monitoring winding and bearing temperature. Should protection of the motor be required, we install protection switch with bimetal release (semiconductor temperature detectors on request). Operating specifications Thermal cut-out

Terminal boxes The location of the terminal box in standard design is on top; on the right or on the left are possible. All motors have removable feet for easy change of terminal box position For motors with mountings IM B6, IM B7, IM B8, IM V5, IM V6 the location of the terminal box is related to an IM B3 mounting. The position of the entry openings can be adjusted to suit the existing connection facilities by turning through 90°. Should special accessories be used (temperature detectors, anticondensation heating, etc.) please enquire. For motors in standard design, the cable gland does not belong to our scope of delivery. For plastic terminal boxes, only plastic glands may be used (shock protection). When using screened leads, a metal terminal box is required. Direction of cable entries

Connection diagrams Windings of standard three-phase single speed motors can be connected either in star or delta connection. Star connection A star connection is obtained by connecting W2, U2, V2 terminals to eachother and the U1, V1, W1 terminals to the mains. The phase current and voltage are: Iph = In ; Uph = Un / 3 where In is the line current and Un the line voltage referred to the star connection. Delta connection A delta connection is obtained by connecting the end of a phase to the beginning of the next phase. The phase current Iph and the phase voltage Uph are: Iph = In / 3 ; Uph = Un where In and Un are referred to the delta connection.

Star-delta starting Star-delta starting allows a peak current reduction. It can be used only when the reduced starting torque obtained is higher than the resistant torque. Actually, it should be noted that the torque of an induction squirrel-cage motor is directly proportional to the square of the voltage. Motors whose rated voltage with delta connection corresponds to the mains voltage, can be started with the star-delta method. All motors can be supplied with windings designed for star-delta starting (for example: 400 V / 690 V Y).

Pole-changing motors Standard pole-changing motors are designed for single voltage and direct-on-line starting. When the ratio between the two speeds is from 1 to 2, the standard motors have one single winding (Dahlander connection). For the other speeds, the motors have two separate windings.

Motors frame sizes 90 upwards in standard design are suitable for operation on static frequency converters, taking into account the following remarks: · Maximum converter output voltage 500V at peak voltages Û 1460V and du/dt 13 kV/us. For higher converter output voltages or stresses, a special insulation is required. · With square characteristic of the load torque, motors can be driven with their rated torque. · For constant torque, the rated torque of motors with internal cooling must be reduced due to reduced cooling air inlet. Depending on the control range, the use of an external fan would be advisable. · The motors frame sizes 90 ­ 112 are suitable for a maximum output frequency of the converter of 60 Hz (e.g. applications with square torque, control range 1:10, such as pumps and fans). For higher frequencies, a special range with type designation AMI is available on request. From frame size 132 upwards, motors designed /Y 230/400 V, 50 Hz can be operated in delta with a maximum frequency of 87 Hz (observe mechanical limit speed). The motors frame size 56 ­ 80 can be operated on single-phase converters up to maximum 60 Hz. (Special range with type designation AMI for operation on three-phase converters with output voltage 400 V and output frequency &gt; 60 Hz). The electrical values and dimensions of the range AMI in frame size 56 to 112 are identical to AM motors (see data tables pages 37-41).

Noise Depending on the operating point and converter type, converter-fed motors produce between approx. 4 - 10 dB(A) higher noise values than when supplied from the mains. For motors driven with a frequency over 50 Hz, more fan noise is produced. We recommend the use of an external fan.

In enquires and orders for spare parts please state always: Designation of spare part, motor type, mounting arrangement, motor serial number (Product No. when available) Enquires and orders cannot be handled without these data.

Connection diagrams Single-phase motors type AMM and AMME are designed for single-rated voltage; motors type AMD and AMDE for dual voltage. The windings (main and auxiliary winding) are connected to the capacitor supplied with the motor. The direction of rotation can be reversed by inverting the winding ends as follows: - main winding for motors with one supply voltage - auxiliary winding for dual voltage motors

Electronic starting device (SE XX) Single-phase motors with one single capacitor generally have lower starting torques than the full load torque. When higher starting torques are required, the motor is equipped with an additional starting capacitor. It is connected by the electronic starting device (SE XX) in the moment of starting and disconnected automatically proximate to the pull-out torque (see figure). At this point the torque characteristic for the running capacitor (characteristic 2) applies again. Characteristic 1 is not reversible. The starting capacitor is reconnected only when restarting the motor. In case of overload, characteristic 2 has to be applied.

In enquires and orders for spare parts please state always: Designation of spare part, motor type, mounting arrangement, motor serial number (Product No. (E-No.) when available) Enquires and orders cannot be handled without these data.

For all other supply value, different from 230/400V 50Hz, since the standard rectifier supply is 230V 50/60Hz, and when an inverter supply is used the rectifier has to be separately supplied according to the diagrams:

For AMS (63 ... 160) and AMBY (63 ...112)

MIN VOLTAGE W2 U2 V2 STANDARD BRAKING

MAX VOLTAGE W2 U2 V2 FAST BRAKING

- +

For AMBY 132-160

Supplying the rectifier separately from the motor terminal block allows to reduce the delay of braking; to achieve the fast braking on AMBY132-160 it is necessary to open even the dc side of the brake coil (according to previous figure). In case of pole-changing brake motors: for motor connection see three phase motors section , the brake/rectifier has to be supplied separately. Warning: for the correct supply of both motor and brake refer to the values written on nameplate.

Apart from other information, it is necessary to specify the exact type designation in all enquiries, when ordering spare parts or replacement motors or when asking for documentary information. The type designation of our brake motors comprises 9 points of reference, each of which may consist of several letters and/or numerals. The meaning of each symbol can be seen from the following table. For motors not inlcuded in oru standard range, special symbols may be used which are not listed here Meaning of the symbols Ref. point 1 2 Meaning Type of motor Cooling Description of symbols used for our motors A M G1) MFV1) F BY S Asynchronous motor Surface cooled with external fan, cooling fins Surface cooled without external fan, cooling fins Surface cooled with forced ventilation, cooling fins Three-phase motors with very high-torque ac brake Three-phase motors with high-torque dc brake Three-phase motors with low-torque dc brake
